| 摘 要： | 选用48头配种日龄相近、繁殖性能无显著差异的大约克经产母猪,按胎次、体况等随机分为6个处理,每处理8头。哺乳母猪自由采食,自由饮水。研究哺乳母猪饲粮中分别添加0,40,60,80,100和120g/kg苜蓿草粉对母猪及其仔猪生产性能、血清指标及乳成分的影响。结果表明:(1)添加苜蓿草粉对母猪断奶至发情时间间隔影响不显著(P>0.05),但显著提高了断奶仔猪数和哺乳期仔猪成活率(P<0.05);对母猪泌乳期采食量、仔猪断奶窝重、窝增重、断奶平均个体重、平均个体日增重有极显著影响(P<0.01)。(2)添加苜蓿草粉降低了母猪血清胆固醇、甘油三酯和低密度脂蛋白胆固醇的含量,提高了母猪血清高密度脂蛋白胆固醇含量和母猪、仔猪血清胰岛素含量,但组间无显著差异(P>0.05)。(3)添加苜蓿草粉对乳中胰岛素样生长因子有一定提高,但差异不显著(P>0.05)。研究认为,添加苜蓿草粉对哺乳母猪及其仔猪生产性能有一定改善,且100g/kg添加水平表现突出,因此在妊娠后期和哺乳期母猪饲粮中苜蓿草粉添加量以100g/kg为宜。

| Abstract: | 48 multiparious Yorkshire,whose mating date and reproductive performance were similar,were divided into 6 treatments with 8 replicates per treatment and one sow per replicate according to the body condition and parity.All sows had ad-lititum access to feed and water.0,40,60,80,100,120 g/kg alfalfa meals were respectively added to 6 groups.The experiment was conducted in order to study the effects of adding different alfalfa meals to lactating diet on performance and serum items of sows and their piglets,and milk composition.The results showed that:(1) There were no significant difference in interval between ablactation and oestrus (P>0.05);Weaning piglets and survival rate were significantly improved during lactation period when amount of alfalfa meal was increased (P<0.05);Feed intake during the lactating sows,weaning litter weight,litter weight gain,weaning average individual weight and average individual daily weight gain of piglets were significantly enhanced (P<0.01).(2) Serum cholesterin,triglycerides and lower density cholesterin concentration of sows were decreased,and at the same time,the level of serum high density cholesterin of sows and insulin of sows and piglets were increased because of adding alfalfa meal to lactating diet,but no significant difference was observed in them (P>0.05).(3) Insulin-like growth factor in milk of sows was improved to a certain extent,but there was no significant difference ((P>0.05)).The study showed that adding alfalfa meal to diet of sows improved the performance of lactating sows and suckling piglets and the effect was significant when additive amount came to 100 g/kg.So it was recommended that the suitable additive content of alfalfa meal in diet of later pregnancy and lactatiing sows was 100 g/kg. |
